*1

Current is typical rms except for spin up.

*2

Power requirements reflect nominal values for +12V and +5V power.

*3

Idle mode is in effect when the drive is not reading, writing, seeking, or executing any commands. A portion of the R/W circuitry is powered down,
the spindle motor is up to speed and the Drive ready condition exists.

*4

R/W mode is defined as 50% read operations and 50% write operations on a single physical track.

*5

Seek/W/R mode is defined as 33% seek operations, 33% write operations, and 33% read operations.

*6

Energy efficiency based on the Law concerning the Rational Use of Energy indicates the value obtained by dividing power consumption by the storage
capacity. (Japan only)
